Be it known that 1, DAVID (J. VILLIAMS, of Cambridge, in the county ofMiddlcsex and State of Massachusetts, have invented certain new anduseful Improvements in Devices to Teach Reading and Sending of TelegraphMessages of which the following is a specification.

My invention relates to a device or game by which one may reproduce thesuccession of sounds or taps which make up each character of thetelegraph-code. I attain this by the mechanism illustrated in theaccompanying drawing, in which- A is a card of pasteboard or othersuitable material. The edge or edges of this card are so notched that ifa strip of pliable material B is drawn across the notched edge thesuccession of sounds or taps produced will reproduce some character ofthe telegraph-code.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

In a card of suitable material, a combination of notches so cut and soplaced on the edge or el'lges, that the succession of sounds or tapsproduced by a strip of pliable material being drawn across the notchededge will reproduce some corresponding character or characters of thetelegraph-code.

In testimony whereof I have allixed mysignature in presence of twowitnesses.
